Modeling and Control of a Standalone PMSG Wind Generation System to Extract the Maximum Power Based on Direct Power Control

This chapter presents a control strategy for a standalone wind generation system based on a permanent magnet synchronous generator (PMSG), in order to extract the maximum electrical power under varying wind speed and apply the maximum power point tracking (MPPT) principle. This chapter is useful to simulate and model the wind energy conversion system (WECS) connected with DC load using MATLAB/Simulink environment. A direct power control (DPC) strategy is adopted for the generator side converter to rectify the PMSG voltage output. Also, a novel PI-control is presented to keep DC bus voltage constant. The results of the simulation presented show the effectiveness and the good reliability of the control strategy used for the power transfer.
